FIELD OF INVENTION

This invention is in the field of wheat (Triticum aestivum L.) breeding, specifically relating to a wheat variety designated 6PRUL80B.

BACKGROUND OF INVENTION

There are numerous steps involving significant intervention in the development of any novel, desirable plant germ plasm. The goal is to combine in a single variety an improved combination of desirable traits from the parental germ plasm. These traits may include, but are not limited to, higher seed yield, resistance to diseases and/or insects, tolerance to drought and/or heat, altered milling properties, abiotic stress tolerance, improvements in compositional traits, and better agronomic characteristics.

Wheat is grown worldwide and is the most widely adapted cereal. There are five main wheat market classes. They include the four common wheat (Triticum aestivum L.) classes: hard red winter, hard red spring, soft red winter, and white (hard and soft). The fifth class is durum (Triticum turgidum L.). Common wheats are used in a variety of food products such as bread, cookies, cakes, crackers, and noodles. In general, the hard wheat classes are milled into flour used for breads and the soft wheat classes are milled into flour used for pastries and crackers. Wheat starch is also used in the paper industries, as laundry starches, and in other products.

DETAILED DESCRIPTION

The present invention relates to a new and distinctive wheat (Triticum aestivum L.) variety designated 6PRUL80B, its seeds, plants, plant parts and hybrids. Variety 6PRUL80B represents a significant advancement in elite germplasm.

Also provided are methods for making 6PRUL80B that comprise crossing wheat variety 6PRUL80B with another wheat plant and processes for making a wheat plant containing in its genetic material one or more traits introgressed into 6PRUL80B through backcross conversion and/or transformation or genetic modification, and to the wheat seed, plant and plant parts produced thereby. Variants of wheat 6PRUL80B created by mutagenesis or transformation, such as genetic modification, as well as a hybrid wheat seed, plant or plant part produced by crossing the variety 6PRUL80B or a locus conversion of 6PRUL80B with another wheat variety are also provided.

Wheat variety 6PRUL80B has shown uniformity and stability for all traits, as described in the variety description information provided herein. It has been self-pollinated a sufficient number of generations, with careful attention to uniformity of plant type to ensure homozygosity and phenotypic stability. The line has been increased with continued observation for uniformity. No variant traits have been observed or are expected in 6PRUL80B, as described, for example, in Table 2 at the end of this section.

Field crops are bred through techniques that take advantage of the plant's method of pollination, such as self-pollination, sib-pollination or cross-pollination. As used herein, the term cross-pollination includes pollination with pollen from a flower on a different plant from a different family or line and does not include self-pollination or sib-pollination. Wheat plants (Triticum aestivum L.), are recognized to be naturally self-pollinated plants which, while capable of undergoing cross-pollination, rarely do so in nature. Thus intervention for control of pollination is needed for the establishment of superior varieties.

Provided are methods of producing progeny with a new combination of genetic traits by cross pollinating one wheat plant with another by emasculating flowers of a designated female plant and pollinating the female parent with pollen from the designated male parent. Suitable methods of cross-pollination of wheat plants are described, for example, in U.S. Pat. No. 8,809,654, which is herein incorporated by reference, but other methods can be used, or modified, as is known to those skilled in the art.

A cross between two different homozygous lines produces a uniform population of hybrid plants that may be heterozygous for many gene loci. A cross of two heterozygous plants each that differ at a number of gene loci will produce a population of plants that differ genetically and will not be uniform. Regardless of parentage, plants that have been self-pollinated and selected for type for many generations become homozygous at almost all gene loci and produce a uniform population of true breeding progeny. The term “homozygous plant” is hereby defined as a plant with homozygous genes at 95% or more of its loci.

Choice of breeding or selection methods depends on the mode of plant reproduction, the heritability of the trait(s) being improved, and the type of variety used commercially (e.g., F1 hybrid variety, pureline variety, etc.). For highly heritable traits, a choice of superior individual plants evaluated at a single location will be effective, whereas for traits with low heritability, selection can be based on mean values obtained from replicated evaluations of families of related plants. Popular selection methods which can be used include pedigree selection, modified pedigree selection, mass selection, and recurrent selection.

The complexity of inheritance influences choice of the breeding method. For example, pedigree breeding, backcross breeding, single seed descent, and bulk breeding, which are each described in U.S. Pat. No. 8,809,654 (incorporated herein by reference), can be used. Each wheat breeding program may include a periodic, objective evaluation of the efficiency of the breeding procedure. Evaluation criteria vary depending on the goal and objectives, but may include gain from selection per year based on comparisons to an appropriate standard, overall value of the advanced breeding lines, and number of successful varieties produced per unit of input (e.g., per year, per dollar expended, etc.).

Various recurrent selection techniques can be used to improve quantitatively inherited traits controlled by numerous genes. The use of recurrent selection in self-pollinating crops depends on the ease of pollination and the number of hybrid offspring from each successful cross. Recurrent selection can be used to improve populations of either self- or cross-pollinated crops. A genetically variable population of heterozygous individuals is either identified or created by intercrossing several different parents. The best plants are selected based on individual superiority, outstanding progeny, or excellent combining ability. The selected plants are intercrossed to produce a new population in which further cycles of selection are continued. Plants from the populations can be selected and selfed to create new varieties.

Wheat variety 6PRUL80B can be used as the female or the male parent in biparental crosses in order to develop new and valuable wheat varieties or hybrids. Wheat normally self-pollinates in nature. Cross pollination of one wheat plant with another to produce progeny with a new combination of genetic traits, can be carried out according to methods known to those skilled in the art. Wheat cross-pollination is achieved by emasculating flowers of a designated female plant and pollinating the female parent with pollen from the designated male parent. Methods of cross-pollinating wheat plants for use in selection and advancement are described, for example in U.S. Pat. No. 9,282,712, the disclosure of which is incorporated herein by reference in its entirety.

Plant breeding methods may include analysis , comparison and characterization of the plant genome and the use of molecular markers, including techniques such as Starch Gel Electrophoresis, Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs), Single Nucleotide Polymorphisms (SNPs) and Quantitative Trait Loci (QTL) mapping.

Molecular markers can also be used during the breeding process for the selection of qualitative traits. For example, markers closely linked to alleles or markers containing sequences within the actual alleles of interest can be used to select plants that contain the alleles of interest during a crossing or backcrossing breeding program. The markers can also be used to select for the genome of the recurrent parent and against the markers of the donor parent. Using this procedure can minimize the amount of genome from the donor parent that remains in the selected plants. It can also be used to reduce the number of crosses back to the recurrent parent needed in a backcrossing program.

The production of double haploids can also be used for the development of homozygous lines in the breeding program and in the production of, for example, hybrid wheat using variety 6PRUL80B. Double haploids are produced by the doubling of a set of chromosomes (1N) from a heterozygous plant to produce a completely homozygous individual. This can be advantageous because the process omits the generations of selfing needed to obtain a homozygous plant from a heterozygous source. Hybrid wheat can be produced, for example, in methods utilizing cytoplasmic male sterility, nuclear genetic male sterility, chemicals, genetic modification or a combination thereof.

Wheat variety 6PRUL80B can be crossed with one or more parental lines, followed by repeated selfing and selection, producing many new genetic combinations. Selected germ plasm can be grown under unique and different geographical, climatic and soil conditions with further selections being made during and at the end of the growing season.

Wheat varieties that are highly homogeneous, homozygous and reproducible are useful as commercial varieties. There are many analytical methods, such as those described herein, which can be used to determine the homozygotic stability, phenotypic stability, and identity of these varieties produced or derived from variety 6PRUL80B. Gel electrophoresis is particularly useful in wheat. Wheat variety identification can occur, for example, through electrophoresis of gliadin, glutenin, albumin and globulin, and total protein extracts.

Disclosed are plant breeding methods in which plant populations as well as individual plants are evaluated for general health, agronomics, and stability at one or more stages. These evaluations can include, but are not limited to, one or more of the following characteristics: plant architecture traits such as seedling coleoptile length, coleoptile color (presence of anthocyanin), juvenile plant growth habit, tillering, plant height, straw strength or lodging, flag leaf carriage at boot stage, leaf width and length, glaucosity of stems, leaves and spikes, pubescence of leaves and spikes, spike shape, spike density, spike awnedness, and plant color through-out stages of growth; plant growth characteristics, such as vernalization requirement, date for first stem joint emergence, heading date, flowering date, physiological maturity date and harvest maturity; tolerance to weather conditions, such as cold tolerance, resistance to heaving, tolerance to wet soils and standing water, drought and heat tolerance; and grain characteristics, such as grain yield, test weight, 1000 kernel weight, grain moisture, grain color, grain shape, grain protein, flour milling yield and baking characteristics.

During its development, wheat variety 6PRUL80B was assayed and/or planted in field trials and evaluated for a variety of traits and/or characteristics as compared to check varieties. The property(s) of appropriate check varieties include but are not limited to varieties with a similar relative maturity, varieties known to be susceptible to one or more particular diseases, insect, pathogen, field condition, weather condition, soil type or condition, and/or crop management practice, varieties known to be tolerant or resistant to one or more particular diseases, insect, pathogen, field condition, weather condition, soil type or condition, and/or crop management practice, varieties comprising one or more particular marker locus, and/or varieties derived from another appropriate variety or having a particular pedigree. Appropriate choice of check varieties for comparison assures an appropriate baseline and valid qualitative or quantitative assessment of any test varieties.

In the development of 6PRUL80B, the plants can be tested for various traits including, but not limited to grain yield, test weight, heading date, harvest maturity, plant height, straw strength, pre-harvest sprout tolerance, resistance levels to leaf rust, stripe rust, tan spot, Septoria tritici blotch, Stagnospora nodorum blotch, powdery mildew, Fusarium (scab), wheat yellow mosaic virus and soilborne mosaic virus, and grain characteristics such as flour yield, flour protein, and baking characteristics.

Wheat variety 6PRUL80B, being substantially homozygous, can be reproduced by planting seeds of the line, growing the resulting wheat plants under self-pollinating or sib-pollinating conditions, and harvesting the resulting seed, using techniques familiar to the agricultural arts.

In one aspect, wheat plants, plant parts and seeds are provided which have all or essentially all of the characteristics set forth in Table 2. In one aspect, wheat plants, plant parts and seeds are provided which have all or essentially all of the physiological and morphological characteristics of wheat variety 6PRUL80B, or all or essentially all of the phenotypic characteristics of wheat variety 6PRUL80B, representative seed having been deposited as disclosed herein.

Wheat variety 6PRUL80B can be further reproduced by tissue culture and regeneration. Tissue culture of various tissues of wheat and regeneration of plants therefrom is well known and widely published. Thus, in another aspect provided are cells which upon growth and differentiation produce wheat plants capable of having the physiological and morphological characteristics of wheat variety 6PRUL80B.

As used herein, the term “plant parts” includes, without limitation, plant protoplasts, plant cell tissue cultures from which wheat plants can be regenerated, plant calli, plant clumps, plant cells, embryos, pollen, ovules, pericarp, seed, flowers, florets, heads, spikes, stems, stalks, leaves, roots, root tips, anthers, and the like. When indicating that a plant is crossed or selfed this indicates that any plant part of the plant can be used. For instance, the plant part does not need to be attached to the plant during the crossing or selfing, only the pollen might be used.

In one aspect, a wheat plant containing a locus conversion or an essentially derived variety of 6PRUL80B is provided. Essentially derived varieties may be obtained, for example, by the selection of a natural or induced mutant, or of a somaclonal variant, the selection of a variant individual from plants of the initial variety, backcrossing, or transformation by genetic engineering, from the repeated use of variety 6PRUL80B or being predominately derived from variety 6PRUL80B.

A locus conversion refers to plants within a variety that have been modified in a manner that retains the overall genetics of the variety and further comprises one or more loci with a specific desired trait, such as male sterility, insect, disease or herbicide resistance. Examples of single locus conversions include mutant genes, transgenes and native traits finely mapped to a single locus. One or more locus conversion traits may be introduced into a single wheat variety.

Transgenes and transformation methods provide means to engineer the genome of plants to contain and express heterologous genetic elements, including but not limited to foreign genetic elements, additional copies of endogenous elements, and/or modified versions of native or endogenous genetic elements, in order to alter at least one trait of a plant in a specific manner. Any heterologous DNA sequence(s), whether from a different species or from the same species, which are inserted into the genome using transformation, backcrossing, or other methods known to one of skill in the art are referred to herein collectively as transgenes. The sequences are heterologous based on sequence source, location of integration, operably linked elements, or any combination thereof. One or more transgenes of interest can be introduced into wheat variety 6PRUL80B.

In some examples, transgenic variants of wheat variety 6PRUL80B are produced by introducing at least one transgene of interest into wheat variety 6PRUL80B by transforming wheat variety 6PRUL80B with a polynucleotide comprising the transgene of interest. In other examples, transgenic variants of wheat variety 6PRUL80B are produced by introducing at least one transgene by introgressing the transgene into wheat variety 6PRUL80B by crossing.

In one example, a process for modifying wheat variety 6PRUL80B with the addition of a desired trait, said process comprising transforming a wheat plant of wheat variety 6PRUL80B with a transgene that confers a desired trait is provided. In other examples, the genome of wheat variety 6PRUL80B is transformed by genetic modification using techniques described herein, such as the CRISPR/Cas system adapted for use in plants. Therefore, transgenic wheat variety 6PRUL80B cells, plants, plant parts, and seeds produced from this process are provided. In some examples one or more desired traits may include traits such as herbicide resistance, insect resistance, disease resistance, decreased phytate, modified fatty acid profile, modified fatty acid content, carbohydrate metabolism, protein content, or oil content.

Numerous methods for plant transformation are known in the art, including biological, such as the use of Agrobacteria, and physical, such as biolistic and particle bombardment, plant transformation protocols. In addition, expression vectors and in vitro culture methods for plant cell or tissue transformation and regeneration of plants such as those known in the art can be used.

In general, methods to transform, modify, edit or alter plant endogenous genomic DNA include altering the plant native DNA sequence or a pre-existing transgenic sequence including regulatory elements, coding and non-coding sequences. These methods can be used, for example, to target nucleic acids to pre-engineered target recognition sequences in the genome. Such pre-engineered target sequences may be introduced by genetic transformation such as genome editing or modification. As an example, a genetically modified plant variety can be generated using “custom” or engineered endonucleases such as meganucleases produced to modify plant genomes (see e.g., WO 2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Another site-directed engineering method is through the use of zinc finger domain recognition coupled with the restriction properties of restriction enzyme. See e.g., Urnov, et al., (2010) Nat Rev Genet. 11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. A transcription activator-like (TAL) effector-DNA modifying enzyme (TALE or TALEN) is also used to engineer changes in plant genome. See e.g., US20110145940, Cermak et al., (2011) Nucleic Acids Res. 39(12) and Boch et al., (2009), Science 326(5959): 1509-12. Site-specific modification of plant genomes can also be performed using the bacterial type II CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated) system. See e.g., Belhaj et al., (2013), Plant Methods 9: 39; The Cas9/guide RNA-based system allows targeted cleavage of genomic DNA guided by a customizable small noncoding RNA in plants (see e.g., WO 2015026883A1, incorporated herein by reference).

Plant transformation methods may involve the construction of an expression vector. Such a vector or recombinant construct comprises a DNA sequence that contains a coding sequence, such as a protein and/or RNA coding sequence under the control of or operatively linked to a regulatory element, for example a promoter. The vector or construct may contain one or more coding sequences and one or more regulatory elements.

A genetic trait which has been engineered into the genome of a particular wheat plant may then be moved into the genome of another variety using traditional breeding techniques that are well known in the plant breeding arts. For example, a backcrossing approach is commonly used to move a transgene from a transformed wheat variety into an elite wheat variety, and the resulting backcross conversion plant would then contain the transgene(s).

Various genetic elements can be introduced into the plant genome using transformation. These elements include, but are not limited to genes; coding sequences; inducible, constitutive, and tissue specific promoters; enhancing sequences; and signal and targeting sequences.

Provided are plants genetically engineered or transformed to express various phenotypes of agronomic interest. Expression of genes can be altered to enhance disease resistance, insect resistance, herbicide resistance, agronomic, grain quality, and other traits relative to a comparable wheat plant that does not contain the transformed element or to a comparable non-transformed plant. Transformation can also be used to insert DNA sequences which control or help control male-sterility. DNA sequences native to wheat as well as non-native DNA sequences can be transformed into the wheat plants described herein and used to alter levels of native or non-native proteins. Various promoters, targeting sequences, enhancing sequences, and other DNA sequences can be inserted into the genome for the purpose of altering the expression of proteins. Reduction or increase in the activity of specific genes by genetic transformation or modification can effect gene silencing, gene suppression or gene over expression in the plants described herein.

Many techniques for gene silencing are well known to one of skill in the art, including but not limited to, knock-outs, such as by insertion of a transposable element, antisense technology, (see U.S. Pat. Nos. 5,107,065; 5,453,566; and 5,759,829), co-suppression, RNA interference, virus-induced gene silencing, hairpin structures, ribozymes, oligonucleotide-mediated targeted modification (see, e.g., WO03/076574 and WO99/25853), Zn-finger targeted molecules (see, e.g., WO01/52620; WO03/048345; and WO00/42219), use of exogenously applied RNA (see, e.g., US20110296556), and other methods known to those of skill in the art or combinations of the above methods.

A genetic trait, engineered into a wheat plant using transformation techniques can be transferred into another line using traditional breeding techniques that are well known in the plant breeding arts. The wheat plants described herein can be the donor or the recipient of the transformed genetic trait. For example, a backcrossing approach can be used to move a transgene from a transformed wheat plant to an elite wheat variety to provide resulting progeny comprising a transgene. As used herein, “crossing” can refer to a simple X by Y cross, or the process of backcrossing, depending on the context. The term “breeding cross” excludes the processes of selfing or sibbing.

Transgenic or genetically modified wheat plants described herein can be harvested to produce a foreign or modified protein in commercial quantities. The foreign or modified protein can be extracted from a tissue of interest, such as a seed, or from total biomass by known methods. The approximate chromosomal location of the integrated or modified DNA molecule can be determined from a genetic map generated, for example, via conventional RFLP, PCR, and SSR analysis.

Particular markers used for these purposes may include any type of marker and marker profile which provides a means of distinguishing varieties. A genetic marker profile can be used, for example, to identify plants of the same variety or related varieties or to determine or validate a pedigree. In addition to being used for identification of wheat variety 6PRUL80B and its plant parts, the genetic marker profile is also useful in developing a locus conversion of variety 6PRUL80B.

Methods of isolating nucleic acids from wheat plants and methods for performing genetic marker profiles using SNP and SSR polymorphisms are well known in the art. SNPs are genetic markers based on a polymorphism in a single nucleotide. A marker system based on SNPs can be highly informative in linkage analysis relative to other marker systems in that multiple alleles may be present. Methods for analyzing polynucleotides from plants, plant parts or seeds described herein may include contacting a polynucleotide from the plant, plant part or seed, such as from wheat variety 6PRUL80B with a molecular marker or with modified nucleotides that facilitate sequencing of the polynucleotide. The polynucleotide may be isolated, separated or otherwise obtained from the plant, plant part or seed. Modified nucleotides such as dNTPs may be incorporated with the polynucleotides along with appropriate primers in a reaction mixture that facilitates sequencing. Sequencing can be done using any method known in the art.

A method comprising isolating nucleic acids, such as DNA, from a plant, a plant part, plant cell or a seed of the wheat varieties disclosed herein is provided. The method can include mechanical, electrical and/or chemical disruption of the plant, plant part, plant cell or seed, contacting the disrupted plant, plant part, plant cell or seed with a buffer or solvent, to produce a solution or suspension comprising nucleic acids, optionally contacting the nucleic acids with a precipitating agent to precipitate the nucleic acids, optionally extracting the nucleic acids, and optionally separating the nucleic acids such as by centrifugation or by binding to beads or a column, with subsequent elution, or a combination thereof. If DNA is being isolated, an RNase can be included in one or more of the method steps. The nucleic acids isolated can comprise all or substantially all of the genomic DNA sequence, all or substantially all of the chromosomal DNA sequence or all or substantially all of the coding sequences (cDNA) of the plant, plant part, or plant cell from which they were isolated. The nucleic acids isolated can comprise all, substantially all, or essentially all of the genetic complement of the plant. The nucleic acids isolated can comprise a genetic complement of the wheat variety. The amount and type of nucleic acids isolated may be sufficient to permit whole genome sequencing of the plant from which they were isolated or chromosomal marker analysis of the plant from which they were isolated.

The methods can be used to produce nucleic acids from the plant, plant part, seed or cell, which nucleic acids can be, for example, analyzed to produce data. The data can be recorded. The nucleic acids from the disrupted cell, the disrupted plant, plant part, plant cell or seed or the nucleic acids following isolation or separation can be contacted with primers and nucleotide bases, and/or a polymerase to facilitate PCR sequencing or marker analysis of the nucleic acids. In some examples, the nucleic acids produced can be sequenced or contacted with markers to produce a genetic profile, a molecular profile, a marker profile, a haplotype, or any combination thereof. In some examples, the genetic profile or nucleotide sequence is recorded on a computer readable medium. In other examples, the methods may further comprise using the nucleic acids produced from plants, plant parts, plant cells or seeds in a plant breeding program, for example in making crosses, selection and/or advancement decisions in a breeding program. Crossing includes any type of plant breeding crossing method, including but not limited to crosses to produce hybrids, outcrossing, selfing, backcrossing, locus conversion, introgression and the like.

Favorable genotypes and or marker profiles, optionally associated with a trait of interest, may be identified by one or more methodologies. In some examples one or more markers are used, including but not limited to AFLPs, RFLPs, ASH, SSRs, SNPs, indels, padlock probes, molecular inversion probes, microarrays, sequencing, and the like. In some methods, a target nucleic acid is amplified prior to hybridization with a probe. In other cases, the target nucleic acid is not amplified prior to hybridization, such as methods using molecular inversion probes (see, for example Hardenbol et al. (2003) Nat Biotech 21:673-678). In some examples, the genotype related to a specific trait is monitored, while in other examples, a genome-wide evaluation including but not limited to one or more of marker panels, library screens, association studies, microarrays, gene chips, expression studies, or sequencing such as whole-genome resequencing and genotyping-by-sequencing (GBS) may be used. In some examples, no target-specific probe is needed, for example by using sequencing technologies, including but not limited to next-generation sequencing methods (see, for example, Metzker (2010) Nat Rev Genet 11:31-46; and, Egan et al. (2012) Am J Bot 99:175-185) such as sequencing by synthesis (e.g., Roche 454 pyrosequencing, IIlumina Genome Analyzer, and Ion Torrent PGM or Proton systems), sequencing by ligation (e.g., SOLiD from Applied Biosystems, and Polnator system from Azco Biotech), and single molecule sequencing (SMS or third-generation sequencing) which eliminate template amplification (e.g., Helicos system, and PacBio RS system from Pacific BioSciences). Further technologies include optical sequencing systems (e.g., Starlight from Life Technologies), and nanopore sequencing (e.g., GridION from Oxford Nanopore Technologies). Each of these may be coupled with one or more enrichment strategies for organellar or nuclear genomes in order to reduce the complexity of the genome under investigation via PCR, hybridization, restriction enzyme (see, e.g., Elshire et al. (2011) PLoS ONE 6:e19379), and expression methods. In some examples, no reference genome sequence is needed in order to complete the analysis. Variety 6PRUL80B and its plant parts can be identified through a molecular marker profile. Such plant parts may be either diploid or haploid.

As described herein, genes or coding sequences can be expressed in transformed plants. More particularly, plants can be genetically engineered to express various phenotypes of agronomic interest. A single gene or locus conversion or at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35 or 40 or more genes or locus conversions and less than about 100, 90, 80, 70, 60, 50, 40, 30, 20, 15, or 10 genes or locus conversions may be introduced into a plant or comprised in the genome of the wheat plant. Combinations or stacks of two or more genes or coding sequences described herein can be used. Through the transformation of wheat, the expression of genes can be modulated to enhance disease resistance, insect resistance, herbicide resistance, water stress tolerance and agronomic traits as well as grain quality traits. These traits and the genes and organisms which may be targets are described in U.S. Pat. No. 8,809,554, which is incorporated herein by reference in its entirety for this purpose. Transformation can also be used to insert or modify DNA sequences which control or alter male-sterility. DNA sequences native to wheat can be modified as well as native and non-native DNA sequences can be introduced into wheat and used to modulate levels of native or non-native proteins. The sequences introduced can be heterologous comprising a coding sequence operably linked to a heterologous regulatory element, such as a promoter.

Nos. 5,981,842, 5,780,709, international patent applications WO 92/19731, WO 92/19731 the disclosures of each of which is herein incorporated by reference for this purpose.

In some embodiments, methods of treating 6PRUL80B with a mutagen and the plant produced by mutagenesis of 6PRUL80B are provided. Backcross conversions of wheat variety 6PRUL80B are also described. A backcross conversion occurs when modified or non-native DNA sequences are introduced through traditional (non-transformation) breeding techniques, such as backcrossing. DNA sequences, whether naturally occurring, modified or transgenes, may be introduced using these traditional breeding techniques. Desired traits transferred through this process include, but are not limited to, nutritional enhancements, industrial enhancements, disease resistance, insect resistance, herbicide resistance, agronomic enhancements, grain quality enhancement, waxy starch, breeding enhancements, seed production enhancements, and male sterility. Descriptions of some of the cytoplasmic male sterility genes, nuclear male sterility genes, chemical hybridizing agents, male fertility restoration genes, and methods of using the aforementioned are discussed in “Hybrid Wheat by K. A. Lucken (pp. 444-452 In Wheat and Wheat Improvement, ed. Heyne, 1987). Examples of genes for other traits which can be used with the methods, plants and plant parts described herein include: Leaf rust resistance genes (Lr series such as Lr1, Lr10, Lr21, Lr22, Lr22a, Lr32, Lr37, Lr41, Lr42, and Lr43), Fusarium head blight-resistance genes (QFhs.ndsu-3B and QFhs.ndsu-2A), Powdery Mildew resistance genes (Pm21), common bunt resistance genes (Bt-10), and wheat streak mosaic virus resistance gene (Wsm1), Russian wheat aphid resistance genes (Dn series such as Dn1, Dn2, Dn4, Dn5), Black stem rust resistance genes (Sr38), Yellow rust resistance genes (Yr series such as Yr1, YrSD, Yrsu, Yr17, Yr15, YrH52), aluminum tolerance genes (Alt(BH)), dwarf genes (Rht), vernalization genes (Vrn), Hessian fly resistance genes (H9, H10, H21, H29), grain color genes (R/r), glyphosate resistance genes (EPSPS), glufosinate genes (bar, pat) and water stress tolerance genes (Hva1, mtlD). The trait of interest is transferred from the donor parent to the recurrent parent, in this case, the wheat plant disclosed herein. Single gene traits, whether naturally occurring, induced by mutation or genetically altered, may result from either the transfer of a dominant allele or a recessive allele. Selection of progeny containing the trait of interest is done by direct selection for a trait associated with a dominant allele. Selection of progeny for a trait that is transferred via a recessive allele requires growing and selfing the first backcross to determine which plants carry the recessive alleles. Recessive traits may require additional progeny testing in successive backcross generations to determine the presence of the gene of interest.

Methods of developing a backcross conversion 6PRUL80B wheat plant are provided including the step of repeated backcrossing to wheat variety 6PRUL80B. The number of backcrosses made may be 2, 3, 4, 5, 6, 7, 8 or greater, and fewer than 50, 40, 30, 25, 20, 15, 10, 9, or 8. The specific number of backcrosses used will depend upon the genetics of the donor parent and whether molecular markers are utilized in the backcrossing program. Provided are plants and plant populations that are produced from backcrossing methods, transformation, locus conversion, or otherwise produced, and combinations thereof and that retain at least 70%, 75%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8%, or 99.9% or 99.95%, 99.98%, 99.985%, 99.99% or 99.995% of the genetic profile of wheat variety 6PRUL80B. The percentage of the genetics retained in the backcross conversion may be measured by either pedigree analysis or through the use of genetic techniques such as molecular markers or electrophoresis. Such methods and techniques are described in U.S. Pat. No. 8,809,654, the disclosure of which is herein incorporated by reference for this purpose. The backcross conversion or locus conversion developed from this method may be similar to 6PRUL80B for the results listed in Table 2. Such similarity may be measured by a side by side phenotypic comparison, with differences and similarities determined at a 5% significance level, when appropriate in environmental conditions that account for the trait being transferred. For example, herbicide should not be applied in the phenotypic comparison of herbicide resistant backcross conversion of 6PRUL80B when compared back to 6PRUL80B.

Described are methods for using wheat variety 6PRUL80B in plant breeding and plants and plant populations produced by such methods. For example, wheat variety 6PRUL80B can be crossed with another variety of wheat to form a first generation population of F1 plants. This first generation population of F1 plants will comprise an essentially complete set of the alleles of wheat variety 6PRUL80B. Also provided are methods and plants which use transgenic or backcross conversions of wheat variety 6PRUL80B to produce first generation F1 plants.

A method of developing a 6PRUL80B-progeny wheat plant comprising crossing 6PRUL80B with a second wheat plant and performing a breeding method is also described. An exemplary method for producing a line derived from wheat variety 6PRUL80B is as follows. Wheat variety 6PRUL80B is crossed with another variety of wheat, such as an elite variety. The F1 seed derived from this cross is grown to form a homogeneous population. The F1 seed contains one set of the alleles from variety 6PRUL80B and one set of the alleles from the other wheat variety. The F1 genome is 50% variety 6PRUL80B and 50% of the other elite variety. The F1 seed is grown and allowed to self, thereby forming F2 seed. On average the F2 seed would have derived 50% of its alleles from variety 6PRUL80B and 50% from the other wheat variety, but various individual plants from the population can have a much greater percentage of their alleles derived from 6PRUL80B. The F2 seed is grown and selection of plants made based on visual observation and/or measurement of traits. The 6PRUL80B-derived progeny that exhibit one or more of the desired 6PRUL80B-derived traits are selected and each plant is harvested separately. This F3 seed from each plant is grown in individual rows and allowed to self. Then selected rows or plants from the rows are harvested and threshed individually. The selections based on visual observation and/or measurements for desirable traits of the plants, such as one or more of the desirable 6PRUL80B-derived traits are made. The process of growing and selection is repeated any number of times until a homozygous 6PRUL80B-derived wheat plant is obtained. The homozygous 6PRUL80B-derived wheat plant contains desirable traits derived from wheat variety 6PRUL80B, some of which may not have been expressed by the other original wheat variety to which wheat variety 6PRUL80B was crossed and some of which may have been expressed by both wheat varieties but now would be at a level equal to or greater than the level expressed in wheat variety 6PRUL80B. The homozygous 6PRUL80B-derived wheat plants have, on average, 50% of their genes derived from wheat variety 6PRUL80B, but various individual plants from the population would have a much greater percentage of their alleles derived from 6PRUL80B. The breeding process, of crossing, selfing, and selection may be repeated to produce another population of 6PRUL80B-derived wheat plants with, on average, 25% of their genes derived from wheat variety 6PRUL80B, and with various individual plants from the population having a much greater percentage of their alleles derived from 6PRUL80B. Homozygous 6PRUL80B-derived wheat plants that have received 6PRUL80B-derived traits are also provided.

In some instances, selection may or may not occur at every selfing generation, selection may occur before or after the actual self-pollination process occurs, or individual selections may be made by harvesting individual spikes, plants, rows or plots at any point during the breeding process described herein. In addition, double haploid breeding methods may be used at any step in the process. In one aspect, the population of plants produced at each and any generation of selfing, each such population consisting of plants containing approximately 50% of its genes from wheat variety 6PRUL80B, 25% of its genes from wheat variety 6PRUL80B in the second cycle of crossing, selfing, and selection, 12.5% of its genes from wheat variety 6PRUL80B in the third cycle of crossing, selfing, and selection, and so on.

Also disclosed are methods of obtaining a homozygous 6PRUL80B-derived wheat plant by crossing wheat variety 6PRUL80B with another variety of wheat and applying double haploid methods to the F1 seed or F1 plant or to any generation of 6PRUL80B-derived wheat obtained by the selfing of this cross.

Still further, methods for producing 6PRUL80B-derived wheat plants are provided by crossing wheat variety 6PRUL80B with a wheat plant and growing the progeny seed and repeating the crossing or selfing along with the growing steps with the 6PRUL80B-derived wheat plant from 1 to 2 times, 1 to 3 times, 1 to 4 times, or 1 to 5 times. Thus, any and all methods using wheat variety 6PRUL80B in breeding, including selfing, pedigree breeding, backcrossing, hybrid production and crosses to populations are provided. Unique starch profiles, molecular marker profiles and/or breeding records can be used to identify the progeny lines or populations derived from these breeding methods.

Also disclosed are methods of harvesting the grain of variety wheat variety 6PRUL80B and using the grain as seed for planting. Embodiments include cleaning the seed, treating the seed, and/or conditioning the seed. Cleaning the seed includes removing foreign debris such as weed seed and removing chaff, plant matter, from the seed. Conditioning the seed can include controlling the temperature and rate of dry down and storing seed in a controlled temperature environment. Seed treatment is the application of a composition to the seed such as a coating or powder. Seed material can be treated, typically surface treated, with a composition comprising combinations of chemical or biological herbicides, herbicide safeners, pesticides, insecticides, fungicides, nutrients, germination inhibitors, germination promoters, cytokinins, nutrients, plant growth regulators, antimicrobials, and activators, bactericides, nematicides, avicides, or molluscicides. These compounds are typically formulated together with further carriers, surfactants or application-promoting adjuvants customarily employed in the art of formulation. The coatings may be applied by impregnating propagation material with a liquid formulation or by coating with a combined wet or dry formulation. Examples of the various types of compounds that may be used as seed treatments are provided in The Pesticide Manual: A World Compendium, C. D. S. Tomlin Ed., published by the British Crop Production Council. Some specific seed treatments that may be used on crop seed include, but are not limited to, abscisic acid, acibenzolar-S-methyl, avermectin, amitrol, azaconazole, azospirillum, azoxystrobin, bacillus, Bacillus subtilis, Bacillus simplex, Bacillus firmus, Bacillus amyloliquefaciens, Pasteuria genus (e.g. P. nishizawae), bradyrhizobium, captan, carboxin, chitosan, clothianidin, copper, cyazypyr, difenoconazole, etidiazole, fipronil, fludioxonil, fluquinconazole, flurazole, fluxofenim, GB126, Harpin protein, imazalil, imidacloprid, ipconazole, isofavenoids, lipo-chitooligosaccharide, mancozeb, manganese, maneb, mefenoxam, metalaxyl, metconazole, PCNB, penflufen, penicillium, penthiopyrad, permethrine, picoxystrobin, prothioconazole, pyraclostrobin, rynaxypyr, S-metolachlor, saponin, sedaxane, TCMTB, tebuconazole, thiabendaxole, thiamethoxam, thiocarb, thiram, tolclofos-methyl, triadimenol, trichoderma, trifloxystrobin, triticonazole and/or zinc.

Seed varieties and seeds with specific genetic resistance traits can be tested to determine which seed treatment options and application rates will complement such varieties and genetic resistance traits in order to enhance yield. For example, a variety with good yield potential but loose smut susceptibility will benefit from the use of a seed treatment that provides protection against loose smut. Likewise, a variety encompassing a genetic resistance trait conferring insect resistance will benefit from the second mode of action conferred by the seed treatment. Further, the good root establishment and early emergence that results from the proper use of a seed treatment will result in more efficient nitrogen use, a better ability to withstand drought and an overall increase in yield potential of a variety or varieties containing a certain trait when combined with a seed treatment.

The following assays can be used to characterize and/or select a wheat variety such as 6PRUL80B during one or more stages of variety development. Other methods and assays are available and can be used in combination with or instead of the assays described herein.

Stripe Rust Screening.

Stripe rust is a fungal leaf disease that is most common in the mid-southern United States in the early spring. Significant levels of the disease can be found in some seasons anywhere in North America. The infection often mostly occurs on the flag leaf but it may attack the entire plant, including the head. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Some major genes for resistance may be detected using controlled seedling screening experiments inoculated with specific races of the pathogen. There are also molecular markers for QTL linked to some specific resistance genes.

Leaf Rust Screening.

Leaf rust is a fungal leaf disease that is most common in the southern United States in the spring and early summer. Significant levels of the disease can be found in most seasons anywhere in North America. The infection is most damaging when it occurs on the flag leaf but it may attack the entire plant, including the head. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Some major genes for resistance may be detected using controlled seedling screening experiments inoculated with specific races of the pathogen. There are also molecular markers for QTL linked to some specific resistance genes.

Leaf Blight Screening.

Fungal leaf blights, including Tan spot, Septoria tritici blotch, and Stagnospora nodorum blotch, are common in much of the North American wheat growing regions. The infection is most damaging when it occurs on the flag leaf but it may attack the entire plant, including the head. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance.

Scab Screening.

Fusarium head blight or scab is a fungal disease that is common in much of the North American wheat growing regions. Infection occurs during flowering and is most severe when conditions are wet, warm and remain humid. The disease infects flowers on the spike and will spread to adjacent flowers, often infecting most of the developing kernels on the spike. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Infection may be induced in controlled screening experiments where spikes are inoculated with specific spore concentrations of the fungus by spraying the spikes at flowering or injecting the inoculum directly into a flower on each spike. There are also molecular markers for QTL linked to some specific resistance genes.

Powdery Mildew Screening.

Powdery mildew is a fungal leaf disease that is most common in the southern United States in the spring and early summer. Significant levels of the disease can be found in many seasons anywhere in North America. The infection is most damaging when it occurs on the flag leaf but it may attack the entire plant, including the head. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Some major genes for resistance may be detected using controlled seedling screening experiments inoculated with specific races of the pathogen. There are also molecular markers for QTL linked to some specific resistance genes.

Soilborne Mosaic Virus Screening.

Soilborne mosaic virus is transmitted by the vector, Polymyxa graminis, which tends to be most common in low-lying, wet soils; particularly those frequently grown to wheat. Symptoms appear in the spring as light green to yellow mottling along with stunting and resetting plant growth in the most susceptible varieties. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Higher levels of natural infection can be induced for screening by planting wheat annually in the same field to increase the vector level.

Wheat Yellow (Spindle Streak) Mosaic Virus Screening.

Wheat yellow virus is transmitted by the vector, Polymyxa graminis, and is most common during cool weather conditions in the spring. Symptoms appear as light green to yellow streaks and dashes parallel to the leaf veins. Symptoms often fade prior to heading as weather conditions become warmer. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance.

Flour Yield Screening.

The potential average flour yield of wheat can be determined on samples of grain that has been cleaned to standard and tempered to uniform moisture, using a test mill such as the Allis-Chalmers or Brabender mill. Samples are milled to established parameters, the flour sifted into fractions, which are then weighed to calculate flour yield as a percentage of grain weight.

Flour yield “as is” is calculated as the bran weight (over 40 weight) subtracted from the grain weight, divided by grain weight and times 100 to equal “as is” flour yield. Flour yield is calculated to a 15% grain moisture basis as follows: flour moisture is regressed to predict the grain moisture of the wheat when it went into the Quad Mill using the formula

Initial grain moisture=1.3429×(flour moisture)−4.

The flour yields are corrected back to 15% grain moisture after estimating the initial grain moisture using the formula

Flour Yield_((15%))=Flour Yield_((as is))−1.61%×(15%−Actual flour moisture)

Flour Protein Screening.

The protein content as a percentage of total flour may be estimated by the Kjeldahl method or properly calibrated near-infrared reflectance instruments to determine the total nitrogen content of the flour.

Flour protein differences among cultivars can be a reliable indicator of genetic variation provided the varieties are grown together, but can vary from year to year at any given location. Flour protein from a single, non-composite sample may not be representative. Based on the Soft Wheat Quality Laboratory grow-outs, protein can vary as much 1.5% for a cultivar grown at various locations in the same ½ acre field.

Sucrose Solvent Retention Capacity (SRC).

The solvent retention capacity (SRC) of wheat flour measures the ability of the flour to retain various solvents after centrifugation. Sucrose SRC predicts the starch damage and pentosan components, and can be correlated to sugar-snap cookie diameter quality metrics.

Sucrose SRC is a measure of arabinoxylans (also known as pentosans) content, which can strongly affect water absorption in baked products. Water soluble arabinoxylans are thought to be the fraction that most greatly increases sucrose SRC. Sucrose SRC a predictor of cookie quality, with sugar snap cookie diameters decreasing by 0.07 cm for each percentage point increase in sucrose SRC. The negative correlation between wire-cut cookie and sucrose SRC values is r=−0.66 (p<0.0001). Sucrose SRC typically increases in wheat samples with lower flour yield (r=−0.31) and lower softness equivalent (r=−0.23). The cross hydration of gliadins by sucrose also causes sucrose SRC values to be correlated to flour protein (r=0.52) and lactic acid SRC (r=0.62). Soft wheat flours for cookies typically have a target of 95% or less when used by the US baking industry for biscuits and crackers. Sucrose SRC values increase by 1% for every 5% increase in lactic acid SRC. The 95% target value can be exceeded in flour samples where a higher lactic acid SRC is required for product manufacture since the higher sucrose SRC is due to gluten hydration and not to swelling of the water soluble arabinoxylans.

Lactic Acid SRC

Lactic Acid SRC=Lactic Acid Solvent Retention Capacity. Lactic acid SRC measures gluten strength. Typical values are below 85% for “weak” soft varieties and above 105% or 110% for “strong” gluten soft varieties. See the above discussion of protein quality in this section for additional details of the lactic acid SRC. Lactic acid SRC results correlate to the SDS-sedimentation test. The lactic acid SRC is also correlated to flour protein concentration, but the effect is dependent on genotypes and growing conditions. The SWQL typically reports a protein-corrected lactic acid SRC value to remove some of the inherent protein fluctuation not due to cultivar genetics. Lactic acid is corrected to 9% protein using the assumption of a 7% increase in lactic acid SRC for every 1% increase in flour protein. On average across 2007 and 2008, the change in lactic acid SRC value was closer to 2% for every 1% protein.

Molecular Screening

Plants are analyzed at various times throughout the development of 6PRUL80B for specific alleles for scab resistance. As discussed above, and as is known to those skilled in the art, other traits can also be screened by molecular analysis.
